To all whom it may concern: a i

Be it known thatI, CHAnLnsHnNnY NEL- soN, a subject of the King of Great Britain, residing at the town of Vulcan, inthe Province of Alberta, in the Dominion of Canada, have invented certain newana' useful Improvements in Grain-Pickling Machines, of whichthe following is a full description.

, lhis invention relates to improvements in grain pickling machines, and the objects of the invention are to facilitate treating the grain to eradicate smut, rust and like diseases, thereby rendering the grain fit for sowing, to permit ofi the treated grain being readily discharged from the machine, and to permit ofthe liquid utilized in cleaning the grain being retained in the macliineduring the operation of discharging the cleaned grain. v,

Further objects are to eii'ect a ready and efficient drainage of the cleaned grain so that the balance of the solution from one cleaning operation may be effectivelyritilized to clean more grain, and generally to adapt the machine to, better perform the functionsrequired. of it. i iv V With the above and 0th r objects in view, the-invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

1 In the drawings-oi.

Figure 1 is a perspectiveview of theiine proved machine.

Fig. 2 is a transverse section through the same.

Fig. 3 is a longitudinal section through the line 2-2 of Fig. 2.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the improved pickling machine which consists of two chambers 10 and 11, the former of which is completely inclosed, with the exception of the front wall 12 which is angularly disposed at the upper end and provided at the lower end with an opening 13 communicating with the chamber 11.

The chamber 10 is considerably larger than the chamber 11 which is open at the top to permit of grain being readily deli'vered thereto, the front wall 11 of the chamtliejohamber 11.

her 11 extending above the opening provided in the wall 12 of the chamber 10} A plurality. of equidistantly spaced triangular distance pieces 14 are located on the bottom of the chamber 11 and tapered from the backtowardi the front thereof, and are adapted to engage the lower portion 15 of the angular screen 16 1nounted 1n the opening 13. n r t An angularly disposed baffle wall 17 is provided in thechambervlO and overhangs the uppcr end of the screen 16 while the front wall 11" of the chamber ll is also provided Iwith an angular baiiie wall 18 which extends into the said chamber forlan objectwhich will ,be 'made clear hereafterf The upper portions2l) if h elateral walls of the chamber 11; are angularly disposed and converge toward each other where they form a discharge spout 21 designed to facilitate loading the cleaned grain into bags or other like receptacles.

The chamber10iis designed to hold liquid while the chamber 11 receives tl iegra in to be cleaned and these chambers are connected by a ventpipe 22 which preventsa partial vacuum being formed in theclosed chamber 10 during the operation ijof the machine (and thus holding the liquid therein and preventingit from washing through the grain in Themachine is provided with trunnions 2d adapted to be rotatably; supported in bearings of the type described in my United States Patent, 1,206,239, granted. on November 28th, 1916, while the oscillation of the machine is accomplished by the lever 25 mounted on the end walls of the machine. This lever extends below the bottom of the machine and is adapted to rest on the ground to hold the machine in position for receiving the grain.

When the machine is in use the cleaning liquid is poured into the chamber 11 and passes through the screen 16 into the chamber 10. When the desired quantity of liquid has thus been introduced into the machine, the grain to be cleaned is placed in the Specification of letters I atent. Pat efltedfict'sfi; 1

chamber 11 and oscillatory motion is man- 7 screen 16 and thoroughly cleans the grain in the said compartment.

- is discharged into a bag or like container.

During the tipping of the machine the liquid drains through the screen 16 into the chamber 10 and owing to the shape of the screen a large draining surface is provided so that the liquid is quickly returned to the chamber 10.

VVhile the grain is being discharged the baflie Walls 17 prevents any of the liquid from splashing through the screen 16 and during the oscillating of the machine the baflle plate 18 prevents the liquid, entering the chamber 11, from splashing over the outer wall thereof.

lVhen the grain has been thus discharged a further quantity is placed in the chamber 11 and the above operation is repeated.

During the operation of the machine I have found that there is great liability of a partial vacuum being formed in the closed chamber 10, and the atmospheric pressure prevents the cleaning liquid from washing through the grain in the open chamber 11, but by the addition of the vent pipe 22 this objection is entirely eliminated and the cleaning liquid is thus at all times enabled to perform the functions required of it.

As many changes could be made in the above description and many apparently widely different embodiments of my invention within the scope of the claims constructed, without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illustrative and not in a limited sense.

What I claim as my invention is:

1. A grain pickling machine comprising a closed chamber, an open chamber communicating with the closed chamber, a screen of substantially angle shape in cross section between the chambers, means for spacing the screen from the bottom of the open chamber and means for oscillating the machine.

2. A grain pickling machine comprising a liquid chamber, a grain chamber communicating with the liquid chamber, a screen between the said chambersytapered spacing members between the bottom of the screen,

and the grain chamber and means for oscillating the machine.

3. I A grain pickling machine comprising a liquid chamber, a grain chamber communicating with the liquid chamber, a screen in termediate of the chambers, a baflle wall in the liquid chamber overhanging the top of the screen, and means for oscillating the machine.

4. A grain pickling machine comprising a liquid chamber, a grain chamber communicating with the liquid chamber, a screen intermediate of the chamber, an angula rly dis posed baffle wall in the grain chamber and means for oscillating the machine.

5. A grain pickling machine comprising an inclosed liquid chamber, a grain chamber communicating with the liquid chamber,

a screen between the said chambers, a vent pipe operatively connecting the chambers and'means for oscillating the machine.

In witness whereof I have hereunto-set my hand in the presence of two witnesses.
